1.2 struggling to accelerate



Loz H

Loz H

Hi guys

Having a strange problem with accelerating. Its not that it takes forever to get upto speed, its that it feels like its trying stop itself going any faster.

I pulled onto a downhill sliproad earlier, changed to 3rd and put the throttle down, but it just started juddering and wouldn't go any faster than 40mph. I lifted off the throttle and then went back on and it pulled away like usual with no problems.

Joined the motorway and was in 5th at about 65. Went to overtake someone and The same thing happened, until I again pulled off the throttle and back onto It again

Anyone had a similar problem?

Do these things have a MAF !? Sounds similar to when my old MAF went on an old car. Idle was OK, under load it was not happy until it was warm. Turned out to be the oil in the new air filter ruining the sensoe.

Could, however, be coilpack, sparks, HTs, fuel pump or a number of other things..

I had similar problems, turned out it was a faulty injector, got them refurbed and drove like a new car.

Hmm it does seem to go away after its warmed up... its had new plugs, leads & coilpack not too long ago mind

Coil pack, happened to me on my 1.2 (common fault). Brought a new one for £35 and fitted it, job done!

Also, f**k paying £85 for it. Where did you take your car? :S

Was yours OK after the car warmed up? was playing up in every gear on the way back from college just, but as soon as i got the engine temp up normal it was fine

could it be a faulty throttle position sensor i know its probably nothing like a mk1 clio but i had the same problem with mine only it wouldnt let me rev at all and i had to turn the car on and off again for it to work. Just a suggestion and from what i remember it isnt to expensive for a new one

Its a common fault with 1.2's that they have trouble accelerating. This is usually down to the fact that its a 1.2.

Sorry, had to say it. I've got one myself; know how you feel.

Its not the fact its slow to accelerate etc, its the fact it wont​ accelerate when its cold....

I used to have that issue in my old 30k miles Mark 2, wouldn't go away unless I shifted out of gear and back in to it. I put my foot down pulling out of a junction and it would just judder more, no response, nothing.

Sell it.

Shouldn't be slamming the poor thing when its cold anyway. Leave it warm up first.

Mine had an issue where it wouldn't go above 3000 rpm at random intervals, had it on the computer countless times but never found any answers, took it off the road not long after and used it as a field car.

sell it, what? id rather fix it...

No i don't slam it at all, your missing the point. its struggling to get upto & over 2000rpm some days, which makes it extremely difficult to get out of junctions/keep up with traffic/pull onto a motorway

Hey mate, got the same issue with mine as well, i have an 07 Campus 1.2. Did replacing the coils work for everyone else? I'm just worried that it is something with the clutch!

Haha, probably because it's got warmer as the day gets on mate ;) It might just be cold starts? Good luck with it though buddy!

Fault reared its ugly head again.

Only seems to happen in heavy rain, as it was shitty all day untill it stopped raining, then the car seemed to be fine when it warmed/dryed up...

I had a problem with mine like this, whenever it rained and the car got too wet it would lose all power and I could only do about 20mph, had my girlfriends dad to look at it and he said that he taped up two wires out of the ECU which we're getting wet and not connected properly and since that I've not had any troubles.

Mine did this all the time, as soon as the weather got a bit wet!
the seals on the coilpack were fudged so water got in it I guess that caused issues, replaced the coilpack and spark plugs cause it might've damaged them... Absolutely fine :) got another 1.2, same issue, misfiring, not accelerating etc, changed coilpack, sorted, never had another problem,
1.2's are renowned for their coilpack issues iirc so.. Just change it, £40 and no more issues :)
